PENNSYLVANIA, ASSIGNOR T6 STANDARD VACUUM BRAKE 00., or CAMDEN, NEW JERSEY, A CORPORATION on NEW JERSEY .MULTIPLE VALVE Application. filed April 13,

One object of my invention is to provide a novel valve or means for applying or releasing one or more brake chambers or a moving element therein operated by vacuum, on automobiles, aeroplanes or other self-propelled vehicles or the like. 7

Another object of my novel valvular construction is to provide a device which will automatically close when a predetermined vacuum has been created in the brake chambers.

Another object is to provide novel means for operating or releasing the brakes or other vacuum actuated devices with a single control, 'manually or otherwise controlled by the operator. 7

To the above ends, my invention consists of a novel construction of a multiple valve or control valve, wherein the casing thereof has an inlet in its lower portion from the brake chamber or chambers and a valve controlled outlet to a tank having atmospheric pressure or less, the outer portion of said casing in its upper portion above the release valve having entrance ports leading from the atmosphere through a suitable port or ports controlled by said release valve, whereby when said release valve is open, air at atmospheric pressure may flow past the same to the brake chamber or chambers.

My invention further consists of a novel construction of a valve casing having an application valve and a release valve positioned in the upper portion thereof, provision being made for supporting said application valve by diaphragm having its outer periphery suitably'secured between the sections of the valve casing.

By reason of the above novel construction, I am enabled to have the application valve automatically drawn down against its seat, when the vacuum in the two openings is sufiicient to overcome the tension of the operating spring.

it further consists of novel means for operating the valvular elements, and of novel tension devices coacting therewith.

It further consists of a novel construction and collocation of an, application valve and a release valve coacting therewith.

1926. Serial No. 101,694..

For the purpose of illustrating my invention I have shown in the accompanying drawings several forms thereof which are at present preferred by me, since the same have been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention not limited to the precise arrangement and organization of the instrumentalities as herein shown and described.

Figure 1, represents a diagrammatic view of a brake system having my novel multiple valve installed therein.

Figure 2, represents a vertical sectional new of my novel construction of multiple or control valve, certain of the parts being shown in elevation, the application valve being shown seated, and the release valve being shown open.

Figure 3, represents a view similar to Figure 2, but showing the release valve seated, and the application valve unseated.

Figure 4, represents a side elevation, showing the valve casing, and the means for actuating the upper portion thereof.

Figures 5 and 6, represent side elevations of the lower and upper portions of the actuating mechanisms of thevalve casing.

Figure 7, represents aside elevation of the application valve, the release valve and its stem and their adjuncts in detached position.

Figure 8, represents a section on line 88 Figure 7.

Figure 9, represents a horizontal section on line 99 Figure 4.

Similar numerals of reference indicate corresponding parts.

Referring to the drawings I 1 designates my novel construction of valve, the same comprising the casing composed of the upper and lower sections 2 and 3, which are provided with flanges 4t and 5 respectively, which are secured together by anysuitable means the outer periphery of the diaphragm 6 being clamped between said flanges.

The diaphragm 6 has the upper and lower plates 7 and 8 in contact therewith, which are secured together by the screws or other fastening devices 9, there being a port 10 through the middle of said plates and diaphragm whereby communication is had between the upper chamber 11, the interior of the valve casing, and the inlet 12 to the valve casing which leads from the brake chambers 12*, with which said inlet 12 communicates. 14E designates a spring in the chamber 11,

"which tends normally to retain "the dia- =rext'ension belowtheiarms 131by means of the screw lG-and said valve body has a recess 17 thereinQfor'the nut 18 which is secured to the "bottom of the valve stem 19 of the re- -lease=valve-20 which'is provided with the bottom plate 21 and the washer 22.

23 'desi-gnatesxa sleeve for the valve stem =19 whichis'providedwith a bottom flange 24:, said sleeve being pinned or otherwise securedito the va'lve stem 19 of the release valve. The upper end of the'sleeve'23 is slidable in "the tehamber :25 contained within the extension26and within the chamber 25' bearing on thevtop 'of'said-sleeve is'the spring 27, whose lower end rests upon the top of said sleeve, while i itsupper end is engaged by the bottom of the hollow adjusting screw .28, which is threadedz-intothe upper portion of the ex- --tension-26. The washer 29 has a pendent an- --nular-fiangesurrounding the upper portion of the adjustingscrew 28 and bears upon the mpper spring- 30, whose lower end contacts withwthe'wall 31, whereby said washer 29 and spring 30can be adjusted by manipulat inglthemuts '32 on the threaded portion 33* of the stem '19.

-ln theupper portion 2 of the valve casing, are the I inlet-ports 33 for the admission of atmospheric air to the interior of the. cham- -b'er-' 11,=above there'lease valve 20. 34 designates an operating handle whichis suitably secured to "the-upper housing 38 above the member 35 of the upper casing section 2 which has the-stepped or serrated upper edge '36 (se'eFigw5) which coacts with the bottom shnilarly-stepped or serrated portion 37 on the upper housing 38, the latterbeing rotatably mountedonthe member 35.

F-orconvenienoe in construction, I have 'shown'the' ho-using'38 as separate from the 'r ing carrying-the serrated edge 37 but secured thereto by the screw 39, see Figures 2, t-and 6. I v 'l lln Fig-urel-l have shown the brake chambers diagrammatically as connected to the inlet to the lower valve section 3, by the conduit 12, while the connection 15 leads to the tank 15 having therein atmospheric pressure or less. 40 designates a pipe leading :lromthe tank 15 to-the valve casing 41, from which leadsthe' pip'e 42 to the'point 43, but as the valve, per se, constitutes my present invention, a detailed description of the other coactin'g elements is' unnecessary.

The operation isas "follows The parts normally appear as seen in Figure 2. The handle 34 is moved anti-clock wisepvhich tends to compress the spring 30, which causes the washer 29 to be forced upwardly into they-position seen in F ig. ,3, which in -':turn rmoves the valve stem 19 upwardly *COI'ILPIGSSlHgllIG spring 27 until the release valve 20 :isbrought against the-valve seat 8. The'vacu-um-inthe opening 15'213611ClS to keep 7 the application valve 14: sezttedgso that after the release valve is :closed ,an additional movement mustbe givenwto the'handleBl, which would compress the spring 30 to a greaterieX-tent than *seen in Fig. 3, and

through the various parts lift the valve body 13 and the valve 14 fromits seat, permitting 'fl-II fPOHLfiliG chamber e rpassage -12 to be --Cl1"LWil' 111i3O the tank-15*- through the opening or passage 15. When the vacuum in the chamber 12 is such as to cause the daaphragm -6 -to :be drawn-- :lown, which inturn moves the valve body-andwthe application valve ld to a downwardgposition, the application valve 14 Will besseate'd. Astill 'furthe'r movement of the handle 34 inthe same direction would compress the spring 30still further, and the operation would be -.-repeated. By moving =the handle 34in a clock-wise directlon, the tension of the sprin-g3-0- .-1s decreased and the andatmosphericpressure toenter the chamber 1 2anda movement of said handle back to its normal position would cause the release valve 22 to entirely unseat as seen 'inFigure 2 leaving the' chamber 12 open to communicate withtheatmospherethrough the ports 33.
